Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Casio EX-G1 and Fujifilm X-E1 side-by-side from the front, back and top in their relative dimensions. Casio EX-G1 has external dimensions of 104 x 64 x 20 mm (4.09 x 2.52 x 0.79″) and weighs 154 g (0.34 lb / 5.43 oz) (including batteries). Fujifilm X-E1 has external dimensions of 129 x 75 x 38 mm (5.08 x 2.95 x 1.5″) and weighs 350 g (0.77 lb / 12.35 oz) (including batteries).
Below you can see the front-view size comparison of the Casio EX-G1 and the Fujifilm X-E1. Casio EX-G1 is clearly the smaller of the two cameras. Its body is 25mm narrower, 11mm shorter and 18mm thinner than Fujifilm X-E1. As you can tell, actually this is not a fair size comparison since Casio EX-G1 has a built-in lens but Fujifilm X-E1 doesn't. Once you put a lens on X-E1, its thickness will increase significantly.
Here is the back view size comparison of the Casio EX-G1 and Fujifilm X-E1.
Now lets look at the top view comparison of Casio EX-G1 and Fujifilm X-E1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Casio EX-G1 is significantly lighter (196g ) than the Fujifilm X-E1 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on X-E1, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the EX-G1, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the X-E1.
LCD Screen Size and Features
Fujifilm X-E1's 2.80" LCD screen is slightly larger than Casio EX-G1's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
